OBD Pilot turns the data buried in your car's computer into clear answers you can actually act on.
Know what's wrong in seconds.
OBD Pilot reads every control unit in your car and turns cryptic codes like P0301 into plain-English explanations — with how serious it is and what likely caused it.

- Likely causes & typical repair cost
- A single Vehicle Health Score, 0–100

People stopped fearing the check engine light.
“My light came on the night before a road trip. OBD Pilot told me it was a loose gas cap — not the disaster I'd imagined. Saved me a panicked trip to the shop.”
“I'm not a car person at all. Being able to just ask ‘is it safe to drive?' and get a straight answer is genuinely the best part.”
“I brought the PDF report to my mechanic and he took me seriously for once. No more being talked into repairs I don't need.”
Good questions, straight answers.
No. OBD Pilot works with the standard, inexpensive OBD-II adapters already sold everywhere (often called ELM327 adapters). If you have one, you're set — if not, they're about $20 online.
Almost certainly. Every gas and hybrid car or light truck sold in the US since 1996 (and the EU since 2001 for petrol) is required to have an OBD-II port. Full electric vehicles expose less standard data, so support there is more limited.
For short trips, yes. For cars that sit for days at a time, we recommend unplugging the adapter when you're done so it can't slowly draw on your battery. OBD Pilot only reads data — it never sends commands that change how your car runs.
Yes. After a scan, OBD Pilot can clear stored codes — which turns off the check engine light and resets readiness monitors. We show you what's wrong first, because clearing a code without fixing the cause just hides the problem.
No. Scanning for codes and viewing live data are free, forever — and you get three AI diagnoses a month (a plain-English verdict and summary) at no charge. Pilot Pro is an optional subscription that unlocks unlimited AI chat, full diagnoses with likely causes and fixes, photo diagnosis, and AI-enhanced PDF reports.

Yes. Your scan history, chats, and saved vehicles stay on your device. When you use an AI feature, only that request is sent — through our private proxy — to generate the answer; the proxy doesn't log it, and there are no analytics, ads, or tracking.
